Diamond Jubilee: Campers brave wind and rain
Hundreds of thousands of people are lining the banks of the Thames to watch the Queen cruise past on a royal barge escorted by a 1,000-strong flotilla.
The event is being held to mark the monarch's Diamond Jubilee and promises to be the most spectacular nautical event in London for 350 years.
Despite the heavy rain, some enthusiasts spent Saturday night camping along the banks of the river to ensure the best possible view, as Simon Clemison reports.
